AP BIOLOGY

Detailed explanation-1: -ATP: Adenosine Triphosphate The more bonds in a molecule, the more potential energy it contains. Because the bond in ATP is so easily broken and reformed, ATP is like a rechargeable battery that powers cellular process ranging from DNA replication to protein synthesis.

Detailed explanation-2: -Aerobic cellular respiration transforms glucose into ATP in a three-step process, as follows: Step 1: Glycolysis. Step 2: The Krebs cycle (also called the citric acid cycle) Step 3: Electron transport chain.

Detailed explanation-3: -It is the creation of ATP from ADP using energy from sunlight, and occurs during photosynthesis. ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not.

Detailed explanation-4: -In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis. ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.
